Calculus 1: Limits & Derivatives (4 of 27) The Relationship Between the Slope and the Limit (2)

In this video I will explain the relationship between the slope and the limit and how to mathematically write the concept.

Next video in the series can be seen at:

Beautiful. Wow, wow, wow thank you for giving me hope at passing my calculus class. God bless your mind and soul!

One of the best explanation i have ever seen ❤ Thanks a Lot Sir!!!!

[angelaandreszuniga]

I never quite understood how the limits could relate to derivatives and this video just clarified all my confusion

[joshuapatton]

Thank you this was very enlightening to me

[samiulhaque]

why we do not take cases when secant line and tangent line coincide or delta =0

[DaHoKilla]

But why do we need to know the slope of the seacant line at point P, wouldnt the point that the tangent line is on already give us that point? Or is it because to find slope you need to have 2 points?

I did not get one point:
If we already know the slope of the tangent at point P=RISE/RUN, then what was the need of introduction of limit here?
point Q is infinitely close to P, then it is obvious that slope at point Q is almost same as slope at P.
